When I am compiling latest MindPX firmware, it complains:
libtinybson.a: Too many open files
What should I do about it ?
What is your dev platform? MacOS allows a default maximum of 256 open files in all running processes, so you may experience this error if you are using Mac.
You can type
ulimit -S -n 300
to lift up the limit.
And you may need to lift that limit to 350 for building new release ....
